Thanx Kalle.

The model has plenty of power & can spin the wheels easily. I try not to. It grips well, I can't recall if I ever weighed it (don't personally have a scale), probably close to twenty 20 pounds.
I can't think of anything negative to say about it, it works really well. One of these days soon I'll install a DX6 radio so I can mix the pump/valves, make it work even better.
If you haven't heard already, Lars Stahl shut 'er down in September... don't know if he's taking a break to regroup or if he's done forever. Hopefully Leimbach & son will take over his side of it, it'd be a shame to see these simple working, but very durable models disappear from the marketplace. Klaus Leimbach & the late Harald Stahl are the pioneers that got this rc construction model hobby started in the early 90's.
